I'm surprised RDMA users are rare, I guess maybe many are just
working with different code base.

while if I patches QEMU below:
On Fri, Aug 11, 2023 at 3:12 PM J
ort of GDS_NO, but seems qemu side doesn't pass
the info to guest, that's why it is unknown. IMO qemu should pass
GDS_NO if the host is already patched.
Is Intel or anyone already working on the qemu patch? I know it's not
a must, but good to do.
Thx!

no, I'm not using multifs patches, just code reading, I fe
ms ok to me.
I feel it's cleaner to do it with a variable than force conversion of
1 to void *.
It's bound to the cm_id which is newly created a few lines above, so
does not affect core rdma transport.
